Sub data:
Fault The gain calibration of the EXP pressure transducer failed.
Description: The drive gas regulates a stable system pressure of 40-50cmH2O, with
the already calibrated PEEP pressure transducer as reference, during gain calibration
of the EXP pressure transducer.
The EXP transducers E2-potentiometers are adjusted during calibration until the
transducer value is close to system pressure.
Displays on Control panel:
The Fresh Gas Flow digit display shows the pressure measured by the INSP pressure
transducer until a stable pressure is reached.
The Preset O2 Conc. digit display shows the pressure measured by the EXP pressure
transducer until a stable pressure is reached.
The Minute Volume display shows the pressure measured by the PEEP pressure
transducer until a stable pressure is reached.
The Tidal Volume display shows the system pressure (target value).
Values displayed is converted from cmH20 to corresponding A/D-value.
The Exp. Tidal Volume display shows the adjusting transducer value.
Values displayed is converted from cmH20 to corresponding A/D-value.
What to do:
1. Check for leakage in the system.
2. Replace PC 1750 Transducer.
3. Replace PC 1737 Measuring.
4. Replace the Drive gas module.
Fault The second offset calibration of the EXP pressure transducer failed.
Description: The offset adjustments of the INSP pressure transducer E2-
potentiometers is repeated but with a negative offset (-25 cmH2O or -10 cmH2O with
PC1750C) to enable measurement of negative pressures.
Displays on Control panel:
The Tidal Volume display shows the target value: 170 (A/D value for 25 cmH2O).
The Exp. Tidal Volume display shows the adjusting transducer value.
Values displayed is converted from cmH20 to corresponding A/D-value.
What to do: Refer to CAL_PRS_OFFSET_FAIL (... 00 0B ) above.
Fault Calibration of pressure transducer 2 fails (INSP).
Description: Refer to information regarding "Calibrating pressure transducers" in
chapter "Service procedures", section "Calibration".
MEA is responsible for calibration of this transducer.
